ABSTRACT:
For smoothing of the leading edges of sheets disposed on the feed table of a sheetfeeder for a rotary printing machine, a vertically reciprocable rule (3) is provided. Prior to grasping of each sheet by grippers (16), the rule is lowered onto the sheets on the table (1), thereby ironing out waviness, so that the sheets may be evenly and securely grasped by the grippers (16) and correctly fed into the printing machine. In order to position the rule as close as possible to the leading edge of the sheets, the rule has recesses (5, 6) which accomodate the grippers (16) and front gauges (17).
